It does not. It does not uses ports at all. Fail2ban monitors your logfiles and activates the firewall to block IP's that matched your rules.
t.ex. You can block an IP that tried to access https://
<url>
/admin. You can block an IP that used wrong credentials x times to login on an ssh port. Or block one that tried to relay via your mailserver. The duration is configurable and alternative duration can be configured for recidivists.
And yes, you can whitelist IP's to avoid locking yourself out. The possibilities are endless.
